ididit Retrofit Steering Column: 1973 Chrysler B-Body - Manual (Page 9)

Now you can verify function of the turn signal switch & ignition.
Column Electrical Test:
Insert the key and check the position of both left & right turn signals
and dash indicators. Then with key in an off position, check the
4-way flashers; in is on, out is off. Now the brake circuit can be
checked by pressing the brake pedal.
Ignition Test:
Insert the key and check the circuits.
One click back counter clockwise and the accessories should come
on (radio, heater blower, etc.). Now turn two clicks forward, this
should have the accessories on and the ignition system on (coil or
electronic ignition has power). OK this is it!! Check that the vehicle
isn’t in gear!!! Now go to the crank position. The Starter should
engage and vehicle should start.
Steering Wheels:
This column does not accept the stock Chrysler steering wheel.
The top shaft of these columns are the same as a GM passenger
car from 1969-94. If using an aftermarket wheel it will require an
adaptor.
Align the spline and horn cam on the top
of the column with those in the adaptor
and slide it onto the column. A nut has
been provided with your steering column.
The nut will secure the wheel to the top of
the column. The nut on the wheel should
be torqued to 40 ft lbs.
